Question about having to dress the blade often....   Have you checked your feed rate to see how many minutes it takes to move your vise 6 inches?   I find a lot of folks max out the drive speed on their saw which tends to wear the blade down prematurely. I have also purchased used saws that had been geared to run faster than what they should. This also can lead to cupping the blade by driving it into the stone too hard. Feed rate is important to get good cuts and not beat up your machine.

Note:  on small rocks you can often get away with running the saw too fast. Put in a larger rock and all of a sudden, your saw jams halfway through the stone or you get a stone with grooves in it from saw blade binding up.  I pay the price and use the dressing stones sold by most lapidary shops. I cannot keep my 24 inch saw running without occasional dressing, and I was never good at properly hitting a saw blade to sharpen it. I just wound up with a saw that made groovy cuts in my rocks.  just a thought

reply to my earlier post....I believe it might be a Royal One saw based on a picture I discovered on cigarboxrocks.com   Does anyone concur?

I too have this same saw...and have to replace the feed motor to get it working.  Thanks to Craigab for the lead on the Dayton motor.  I've just ordered it.   One question for all::was the manufacturer of the saw ever determined?

Getting ready to satisfy my rockhounding addiction.  I've got my reservations in place for the first two weekends of November for field trips to the Kokernot and Boxcar ranches in Alpine, TX. I'm still working out what to do with the five days in between...from November 7 thru 11. Jean has a hunt on Wednesday on the So. Larremore, but that still leaves four down days. Gotta fill in or head out. Can't sit.
My first thought is to head south and roadside collect around George West, Laredo and Zapata. My only hesitation there is that deer hunting season opens that week. There aren't any state authorized deer hunting areas near my hunting areas that I can see in the state map, but that doesn't mean there can't be hunters. I do have day glo gear.
If anybody has any suggestions please feel free to suggest.

I've cut lots and have just worried about yield and all was fine.

I will be cutting thin slabs of "garden" quartz (a.k.a. lodolite) to use as caps in doublets.

Can I orient the crystal any way I like to maximize yield and aesthetics, or should I expect problems in certain directions of sawing?

I am cross-posting this here to avoid hijacking the "Pictures in stone" thread where this was originally posted.

This round, fist-sized nodule was found in a rock pile with materials from several large estates bought in the 1980s. In other words, could be anything.

There was a small chip revealing tight, high-contrast red banding, so I decided to pick it up. It turned out wonderful, but I would like everyone's opinion on possible locality. Dryhead? Teepee Canyon? Chihuahua? Argentina?

Definitely not a dryhead from those pics.  I am out of town and our new ranch under construction and when I get home will send some dryhead nodule pics from the outside, I'll stick with the Teepee and teepee can have several rind types. 

I guess the other thing may be that the area between Dryhead and Teepee could also have similar agate colorations to the 2 locations.  So much hidden material still to be found for sure.

Steve, have a look and let me know what you think. It was a large, round nodule with some bumps.

Could this be Mexican instead?

Second is mafic intrusive. Look into grading relationships between gabbro, diorite and granite; you'll find something similar in the intermediary classifications. Looks like high silica, plagioclase feldspar and lots of biotite mica. Good luck!

May be gravel fill, may be off a monument- diorites are and were commonly utilized for both 'cause it's tuff stuff!
